“We congratulated the person in question and we gave them some advice, to sign the back of their ticket and to keep their ticket safe.

“The money still needs to be collected from the other countries, the jackpot is pooled of course, so it will certainly be the end of this week before the money arrives in Ireland and we can pay it out.

“So this person has plenty of time to decide when it suits them to come in and collect the money.”

Mr Griffin added that it is the National Lottery not to reveal the exact location of the win when the money in question is so big.

He said: “When they come in we have a booklet that we give to all the big winners, we also have a video which Craig Doyle shot on our behalf given them some tax advice and some professional assistance.

“We’re also here for them if they have any other specific questions or queries.

“They can ring us anytime, we have people who have dealth with a number of these multimillion euro wins now.”

There was huge speculation in Kilmore Quay in Co Wexford over the weekend as rumours circulated that the winning ticket had been bought there.

The only thing on the minds of locals in the small fishing village, was whether or not one of them has won the mammoth stash of cash.

John Brady, owner of the picture postcard village’s new Mace store, had to bat away claims he sold the winning slip on the day of the draw.

Mr Brady described how he’s had to shoot down the rumours all day long.

He said: “I got about four phone calls from different shop owners in Wexford town. They were all asking if I sold the winner.

“But we haven’t been told a thing. I’m sure we would know by now. Everyone coming in is asking if I sold it and I have to tell them that I just don’t know.

“I really hope we did but I can’t say for certain. It’s been on all the local radio stations a shop in Kilmore Quay sold the ticket. But I have to keep telling them otherwise.”

It later emerged the speculation may have been sparked by a Facebook post which showed a group of women enjoying a meal and a drink with the caption: “Spending our Lotto winnings.”

It drove the rumour mill into overdrive in the village of just 414 souls but, as it turns out, the group of women had won €250 and had been spending their syndicate cash on a night out.

But even if Brady’s Mace store did sell the ticket, the owner explained how he wouldn’t have it in him to check the CCTV cameras for the lucky punter.

He added: “I think it would just drive me mad. If the Lotto told me the time it was sold, I’m sure I could see who it was.

“But I just wouldn’t be able to do it. It would have me going mad. It would come out as well. I just wouldn’t be right.”
